New setup looking for large yields

[Opie Yutts]

I figured out that you don't need any of the sophisiticated exhaust stuff, just an AC and a DH and some fart fans going across the lights.

Wow, you figured that out? I wish I could figure out how to use 2200 watts of HID in a 4x4' space, without ventilation. Because an AC and DH damn sure aint going to do it. That is unless you are putting in one of those AC units that are rated to do about 4 rooms.
